| Outline of Final Research Achievements |
In this study, we analyzed in detail the structure and dynamic plasticity of the VNS regulon, a gene expression regulatory system that plants have evolutionarily developed to optimize the function of water conduction and body-support by vascular xylem cells, in a multilayered approach. The results revealed that 1) degradation of a group of proteins is important for the optimization of xylem cell functions, 2) the cell cycle and intracellular environment are deeply involved in the regulation of xylem cell differentiation, and 3) the basic structure of the VNS regulon is conserved in a moss (Sphagnum palustre) and a conifer (Pinus taeda).
